Dispensing valve comprising a valve housing of plastic material for transport - and storage container for liquids and method for the production of the electrically grounded connection flange for fastening the dispensing valve on the dispensing socket of the inner container of the transport - and storage container

摘要

The object of the invention is a dispensing valve (13) comprising a valve housing (18) of plastic material for transport - and storage container for liquids, which has an inner container (2) with a filler neck and a dispensing socket (12) for connection of the dispensing valve (13), an outer circumferential surface of a metal grid or a sheet metal as well as a pallet-like underframe of metal are equipped. The dispensing valve (13) is connected to the inlet connector (20) of the armature housing (18) is constructed as a threaded flange to a connecting flange (21) made of a non-conducting plastic material is screwed on the onto the dispensing socket (12) of the inner container (2) is welded. The connecting flange (21) of the armature housing (18) is connected via a grounding conductor made of an electrically conductive plastic material with the lower frame, or the outer surface of the transport - and storage container connected. The connecting flange (21) and the grounding conductor are obtained by the 2k - technology with a injection molding machine produced in a two step process.In a further embodiment of the dispensing valve, the connecting flange and the grounding cable in one piece from an electrically conductive plastic material is injection molded and the grounding cable by means of a tear film connected to the flange ring of the connection flange.
